Marine Weather and Tide Forecast for Weskan, KS

SHORT TERM /THROUGH SUNDAY/
Issued at 1233 AM MDT Sat Apr 18 2026

This morning, temperatures will be dropping into the 20s across the region. By 14Z, we should have warmed to above freezing temperatures and the Freeze Warning should be allowed to expire on time. For the rest of the day, an 850 mb Colorado high will funnel in northwesterly air into the region, keeping temperatures seasonal, around 60 for highs.

Unfortunately, RH values will be dropping into the low to mid teens again as northwesterly winds gust around 20-30 kts. Most of the area will likely see briefly critical fire weather condition. However, areas generally along and north of U.S. 36 are the only places that currently have at least 80% confidence in hitting these conditions for at least three hours. This has prompted a Red Flag Warning for this portion of the CWA this afternoon.

Tonight, temperatures are forecast to drop to around 30 across the area, and patchy frost is possible. We are not currently looking at issuing a Freeze Warning for tonight to prevent warning fatigue when temperatures look to largely remain within a few degrees of freezing.

Sunday, we warm back up as temperatures climb into the 70s. We'll have a 500 mb ridge building in from the west, which will work to keep the skies most clear, promoting that warming. RH values are forecast to drop to around 10%, but winds largely remain under 20 kts. Greeley and Wichita counties could see some occasional gusts in the 20-23 kts range, leading to briefly critical fire weather condition, however the stronger winds look to remain southwest of the CWA

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Issued at 256 PM MDT Fri Apr 17 2026

Starting Sunday morning, an upper level ridge looks to be moving through the region and exiting around Wednesday to Thursday. At the 850 mb level there looks to be a high pressure system that is located just to the south over Texas extending north over the region. During this period, Sunday looks to have warmer temperatures with highs in the mid to upper 70s and lows in the low 30s to upper 20s. Relative humidity (RH) values look to be in the single digits for majority of the afternoon. Wind Gusts however look to be in the lower teens with Wichita and Greeley counties showing values into the 20-25 mph range. There is also a 30-50% chance of exceeding 25 mph gusts for areas south of I-70. There is some concerns for fire weather especially how low the RH values are but if we were to meet criteria it would mainly be the southern portions of the CWA Monday looks to be dry with the probability of seeing RH values less than 15% being 50-95% with the higher percentages over eastern Colorado.
Wind gusts look to be lower with the probability of exceeding 25 mph only to be in the lower teens and primarily over the southern Kansas portions of the CWA Moving on to Tuesday the pattern looks similar with high temperatures in the mid to upper 80s and lows into the 40s. Winds and RH values look to be very similar with RH values in the lower teens. Wind gusts look to be just below fire weather criteria. However one scenario to look at is that the 90th percentile for the NBM is showing gusts reaching fire weather criteria with gust up to 35 mph. Looking at the spread from 90th- 10th shows there being about a 25 mph difference which lowers the confidence in seeing the winds reach fire weather criteria for both days.

Wednesday looks to be our transition day for weather. Guidance is showing that the ridge moves out and a trough moves in which could bring both precipation chances and fire weather concerns. Looking down to the surface there looks to be a dryline that sets up over our CWA Currently there is some uncertainty on where exactly it will be located as some models show the dry line being over KS Hwy 27 and some show it further eastward over KS Hwy 25. There is a chance to see precipation and fire weather chances on Wednesday.
Looking at the dryline there are dew points in the upper 40s and lower 50s this can help storm potential. Now the dry side of the dryline, there is a signal of seeing fire weather. The wind gusts have a range of 20-45 mph. For the majority of the CWA there is a 50- 90% of exceeding 25 mph for the afternoon. The 90th percentile is also showing up to 55 mph. RH values look to remain in the lower teens for the majority afternoon. Guidance is showing there being 50- 90% of seeing values less than 15%. Looking at GFDI values starting at 18z Wednesday values become higher than 50 and they decrease around 1z Thursday. The peak values arrive around 21z Wednesday with values up to 100. These conditions are showing signs of supporting explosive fire growth potential. Depending on how quickly this system moves through Thursday does look to be similar to Wednesday.
Scenario one is the system moves through the fire weather conditions could be more of a concern for the majority of the CWA, but not as extreme as Wednesday. Scenario two would be the system lingers and the potential for precipation chances becomes a concern especially if there is severe weather potential. As for the location and timing will need more investigation as we get closer to the event.

Friday shows precipitation chances to return with the PoPs being in the 20-30s mainly north of I-70 and West of KS Hwy 27. For temperatures the highs look to be in the 60s and lows in the 30s- 40s. Winds look to be in the 20-40 mph range. One thing to note this is at the end of the forecast period so a lot can change, but there are precipitation chances on the horizon.

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
Issued at 1055 PM MDT Fri Apr 17 2026

VFR conditions will prevail through the period at both KGLD and KMCK. Overnight tonight, winds will favor a west-northwesterly direction, occasionally becoming west-southwesterly. During the day Saturday, northwesterly winds will pick up and gusts in the 20-30 kts range are expected, with the stronger winds at KMCK.
Around sunset, winds will weaken then become southwesterly in the evening hours.

Temperatures colder than what has recently occurred are expected tonight and Saturday night, increasing the icing potential in the early morning hours, but also increasing density altitude during this time.
